This research project attempted to (1) identify leader types from teacher descriptions of the leadership behaviors of elementary school principals and (2) study the effects of the leadership types on the organizational behavior of teachers. Teacher responses from 99 Iowa elementary schools revealed three basic principal leadership types. Using both the Q-sort and analysis of variance techniques, factor analysis of the item description pattern for each type suggested the following labels: Type I--Tolerant-Integrator; Type II--Intolerant-Structuralist; and Type III--Tolerant-Interloper. Under Type I principals, teacher behaviors of disengagement and hindrance were lower, esprit was higher, and congruence between teachers and principals was greater. Principal type was found to be unrelated to both school staff size and organizational intimacy. (RA)
